Mayweather was an acquaintance of 34-year-old Earl Warren Hayes. Police say Hayes shot his wife, 30-year-old Stephanie Elyse Moseley, and then took his own life in their Fairfax-neighborhood apartment on Monday.

Investigators had wanted to talk to Mayweather following media reports that he may have spoken to Hayes before the murder-suicide.

Police have said Hayes and Moseley were estranged but recently had tried to reconcile. They haven't released a motive for the killings.
